The problem with this reasoning is that the SAT isn't an arbitrary test. Presumably the course material came before the SAT was developed to test mastery of the material. Sure, the course material then changes to better capture what the SAT measures, and the SAT adjusts in kind. But this adversarial process doesn't optimize arbitrarily. Learning SAT material (rather than say learning tricks) is learning substantial math and reading skills, the kind that serves you well in college. So characterizing this as anything other than getting an education is disingenuous.
